What are X Points? And Why They are NOT Portals Through Space-Time

As of late I have seen many websites and videos claim that X points are essentially portals through space that humans can take advantage of. Some even go as far to say that X points have transported small space crafts through space-time. I am here today to tell you that all of this is false, but the truth behind X points may be cooler than the embellished stories.

James Webb Space Telescope, The Instrument That Will Help Us Further Understand Our Universe

Many people familiar with space exploration know about the Hubble Space Telescope. The Hubble has enabled us to peer into neighboring solar systems, while also helping us map out our universe. With the creation of the James Webb Space Telescope, it looks like the Hubble won’t be alone in pursuing that task. Watch to learn more.

The Origin of DNA Might Have Came From Space

The origin of DNA might have came from space. How life formed on earth is a mystery the human race has been trying to solve for centuries. What prompted the growth of life on earth? Did it form here? Or did it come from somewhere else? These questions may have an answer, as new studies suggest that the building blocks of DNA could have come from space.

Space Exploration Is Taking A Big Leap Forward With The Creation Of This Nano Spacecraft

Space exploration is taking a big leap forward with the creation of this tiny spacecraft. When we think of spaceships today, we often imagine large rockets with powerful engines flying towards the Earth's atmosphere, but with new advancements in space exploration technology, the way we imagine rockets and other space exploration devices may forever change. Scientists are breaking the mold on the general concept of spaceships by creating a new type of space exploration technology that is only 3.5 centimeters, long and wide. They are called Sprites, and the spacecraft consists of a circuit board, much like the one we would find in today's phones, computers, and other technology, that is modified with sensors to collect data from planets and stars. Watch to learn more.

Alien Life Potentially Forming On Saturn’s Moon

Alien life potentially forming on Saturn’s Moon. Alien life has been a constant topic of debate for many centuries. Some believe we have already been visited by extraterrestrial life, and others believe that notion of aliens existing is pure fantasy. However, with our universe expanding as fast as the speed of light, there has to be something other than us out there right? Recent scientific findings suggest we may have found evidence of otherworldly life in our own solar system. Watch the video to learn more.

Tardigrade, The Animal That Can Survive In Space

Tardigrade, the animal that can survive in space. The tardigrade, also known as the water bear, is one of the most resilient animals ever discovered. They can survive in the vacuum of outer space, the deep sea, and even the highest mountains. In a recent study, scientists tested what would happen to the tardigrade if different apocalyptic scenarios were to occur. To see what, if anything, would spell the doom for this creature's existence. Watch the video to learn more.

Identical Universe Where Time Flows Backwards

Identical Universe Where Time Flows Backwards. Theoretical physicists are now proposing there is an inverse universe where time appears to move backwards not forwards. This universe is said to be an exact copy of ours. So instead of moving from prehistoric history to the digital age, this universe is experiencing the digital age first and progressing towards prehistoric history. Watch the video to learn more.

Is Time Travel Possible? How Gravity Affects Time

Is Time Travel Possible? How Gravity Affects Time. The notion of time travel has surely crossed every human's mind at some point. Imagine being able to go back to the earliest days of civilization, or forward to the unknown future of mankind. Theoretical physicist Albert Einstein was no different but he took his daydreams much further than most. His intelligence and curiosity drove him to discover time as the fourth dimension in his now famous equation E=MC squared. This equation elegantly describes the mysterious force of gravity and how it relatively affects time. Watch to learn more.
